Abstract

Válvula (1) de distribuidor giratorio para servodirecciones de vehículos automóviles, con un primer elemento de válvula que está unido solidariamente en rotación con un miembro de entrada (4) de la válvula, y con un segundo elemento de válvula que está unido solidariamente en rotación con un miembro de salida (5) de la válvula, estando unido el primer elemento de válvula con el miembro de salida (5) de la válvula a través de un muelle de varilla de torsión (9) y a través de un acoplamiento de marcha muerta, estando dispuestos los dos elementos de válvula coaxialmente uno dentro de otro en forma móvil en una carcasa de válvula y pudiendo ser hechos girar uno con relación a otro como máximo en la medida del recorrido de giro del acoplamiento de marcha muerta, y presentado el elemento de válvula radialmente exterior y el elemento de válvula radialmente interior unas ranuras longitudinales de mando (6, 7) interiores y exteriores, respectivamente, limitadas al menos parcialmente en su longitud axial, las cuales pueden ser también de configuración cónica con fines de ajuste de su curva característica y cooperan una con otra para controlar un medio de presión hacia y desde dos cámaras de trabajo de un servomotor.Rotary distributor valve (1) for servodirections of motor vehicles, with a first valve element that is jointly connected in rotation with an inlet member (4) of the valve, and with a second valve element that is jointly joined in rotation with an outlet member (5) of the valve, the first valve element being connected with the outlet member (5) of the valve through a torsion rod spring (9) and through a dead gear coupling , the two valve elements being arranged coaxially one inside the other in a mobile manner in a valve housing and can be rotated with respect to each other as far as the rotation path of the dead gear coupling is concerned, and the element presented of the radially outer valve and the radially inner valve element longitudinal and internal control slots (6, 7), respectively, limited to at least p essentially in its axial length, which can also be of conical configuration for purposes of adjusting its characteristic curve and cooperate with each other to control a pressure means to and from two working chambers of a servomotor.
